BARNETT and J E EL ND NB, i bi eats i e K n of Great Britain, residing at Rugby, "Warwickshire, England, have invented certain new and useful Improvements in Conv'eyer Mechanism Particularly Applicable for Road-Sweeping and Other Machines, and of which, the following is a specification.

This invention refers'to improvements. in

j conveyer mechanism particularly. applicable for road sweeping Ir lacllilrle s l i'a'v i1i'g conveyer mechanismofithekinddescribed in the specification of our patent application Serial No. 1134113, 29th November 1916, that is. to say conveying mechanism comprising a trough, segmental, in crossssection which receivesjtherefiuseor other material to beconveyed (hereafter termedrefuse) to the longitudinal edge of which trough there is fixedthe bootof an elevator casing of less width than the. trough, the said boot and the said trough .con-joiningin such manner that an elevated.idii' idi ng ridge. is formed at the. junction of, said trough and said boot; with'this construction two oppositely inclined helical blades ,are. carried in said trough'by a revolving shaft, the saidv helical blades meeting on the. shaft opposite the center of the boot of the elevator and operating not only to move the refuse along the trough to a position opposite. the 'boot of the GQ WBYQIQ but acting also to transfer therefuse from the trough over the dividing ridgei-nto the boot of the elevator.

Now it has been found that the. refuse is liable to collect on theridge between the segmental trough and the boot of the elevator and such refuse, graduallyaccumulating on the. r g fermsan s r ct n t re lar action of the conveyer mechanism: The

object of the invention is to provide simple and efiicient means for overcoming this defect.

The invention will be described with reference to the accompanying drawings as applied to a road sweeping machine, Figure 1 being a vertical section of the rear portion of such a. machine fitted according to the present invention, and Fig. Qis apart plan view of same.

The road sweeping machine illustrated in the drawings. is of the kind referred to in the specification of. our patent application Serial No. 134113 aforesaid, that is to say Specification ofletters Eaten-t.

it comprises a framework 1 carrying a, circular revoluble road brush 2 by which the refuse isdelivered into a segmental trough '3, through whichextends a shaft 4 carrying Opposite direction, the helical blades extending. from the ends of the segmental trough 3;to,oppo site the centerof the boot 7; of an elevator'which is fixed to the trough 3 so that an elevated ridge is, formed between the trough?) and theelevatorb'o'ot The two helical blades 5 and 6 fixed on the shaft 4. meet opposite. the center of the conveyer boot 7, and these blades act at their meeting place to transfer the refuse from the segmental trough 3- to the boot 7 of an in c'lined; elevator casing which contains con- Veni'entelevating mechanism 8.' The road brush. 2, the helical blade-carrying shaft 4, and the chain of the elevator are drivenin any convenient manner and usually by driving chains from the road wheels of the machine, which are notfillustra'ted in the accompanying drawings.

It will however be observed that the refuse in being. transferred from the segmental trough '3 by the helical'blades into the boot 7 of the elevator, must pass over the ridge 9 between the said trough 3 and the said b ot ?-v Now according to the present invention a revoluble roller 10 is, located upon this ridge, and in the drawing at Fig. 1 the roller 10 is accommodated infa segmental recess formed on the ridge 9, being carried in suitable bearings', so. that the roller 10 is capa ble of turning about its axis as the refuse passes over, and the surface of the roller '10 is subjected to a constant scraping action during its revolution by the edges of the recess in which it partly enters. I

Generally we find that the roller '10 acts most advantageously when positively driven from some moving part and so mechanically caused to have a constant revolution about its axis, and to this end we connect the axis of the roller 10 with some convenient revoluble shaft, by say sprocket wheels and a chain 11, and the roller can conveniently be driven from the shaft 12 carrying the lower sprocket wheel 13 of the elevator.

By this invention any collection of refuse on the connecting ridge between the conminers which has been liable to such in- {a anaemi -ha m n r crease as to bejdeti imental to the o ration of the machine, is nowentirely, obviated.
